How to separate a single column file into files of the same size (i.e. number of rows)?
I have a text file with 1,000,000 rows (It is a single column text file of numbers). I would like to separate the text file into 100 files of equal size (i.e. number of rows). The first file will contain the first 10,000 rows, the second row will contain the second 10,000 rows (rows 10,001-20,000) and so on.... How do I go about doing this? Thanks!

pnmscalefixed
pnmscalefixed(1) General Commands Manual pnmscalefixed(1)
NAME
pnmscalefixed - scale a portable anymap quickly, but less accurate
DESCRIPTION
pnmscalefixed is the same thing as pnmscale except that it uses fixed point arithmetic internally instead of floating point, which makes it
run faster. In turn, it is less accurate and may distort the image.
Use the pnmscale man page with pnmscalefixed. This man page only describes the difference.
pnmscalefixed uses fixed point 12 bit arithmetic. By contrast, pnmscale uses floating point arithmetic which on most machines is probably
24 bit precision. This makes pnmscalefixed run faster (30% faster in one experiment), but the imprecision can cause distortions at the
right and bottom edges.
The distortion takes the following form: One pixel from the edge of the input is rendered larger in the output than the scaling factor
requires. Consequently, the rest of the image is smaller than the scaling factor requires, because the overall dimensions of the image are
always as requested. This distortion will usually be very hard to see.
pnmscalefixed with the -verbose option tells you how much distortion there is.
The amount of distortion depends on the size of the input image and how close the scaling factor is to an integral 1/4096th.
If the scaling factor is an exact multiple of 1/4096, there is no distortion. So, for example doubling or halving an image causes no dis-
tortion. But reducing it or enlarging it by a third would cause some distortion. To consider an extreme case, scaling a 100,000 row image
down to 50,022 rows would create an output image with all of the input squeezed into the top 50,000 rows, and the last row of the input
copied into the bottom 22 rows of output.
pnmscalefixed could probably be modified to use 16 bit or better arithmetic without losing anything. The modification would consist of a
single constant in the source code. Until there is a demonstrated need for that, though, the Netpbm maintainer wants to keep the safety
cushion afforded by the original 12 bit precision.
pnmscalefixed does not have pnmscale 's -nomix option.
